Abstract
It is repeatedly proved that the application of the radiant heating system is cost-effective. The most energy-efficient solution is the use of gas infrared emitters. In this case, there is no intermediate heating medium, and the heat of combustion of the gas enters the premises. However, this solution has a number of restrictions on the availability of natural gas, comfort, and fire hazard. Also, a highly efficient solution is the use of water infrared emitters, which can be radiant panels or radiant profiles that use an intermediate heating medium but do not have many of the limitations inherent in gas systems. A common problem for all types of radiant heating is the lack of a scientifically grounded and generally accepted engineering methodology for its design. Most of the regulatory documents simply do not take into account the peculiarities of the operation of radiant heating systems and, thus, do not allow a number of its advantages to be realized. This research was carried out based on NNGASU Radiant Heating Laboratory, unique in Russia, and is devoted to the peculiarities of the formation of the temperature regime in the premises heated by water infrared emitters, as well as the thermal regime of external enclosing structures in these premises.
Highlights
Due to the constantly increasing energy prices and the growing technological requirement for energy is, the problem of energy conservation is one of the most acute in the construction industry, in Russia, but throughout the world [1]
The fundamental difference between heating systems based on infrared emitters is that heat is supplied to the working area by a directed flow of thermal radiation [4]
The air is transparent to electromagnetic radiation in the infrared spectrum, only scattering it, and the energy from the infrared emitters accumulates on the near-surface layers of the irradiated surfaces, and forms convective flows that heat the air of the working area
Summary
Due to the constantly increasing energy prices and the growing technological requirement for energy is, the problem of energy conservation is one of the most acute in the construction industry, in Russia, but throughout the world [1]. The air is transparent to electromagnetic radiation in the infrared spectrum, only scattering it, and the energy from the infrared emitters accumulates on the near-surface layers of the irradiated surfaces, and forms convective flows that heat the air of the working area. These features indicate a fundamental difference from convective heating systems and lead to an increase in energy efficiency [5]
